The court was told there had been an argument over claims he had used a sponge which Mrs Middleton-Potter kept for washing her dogs - and allegedly left it in a dirty state.

She said Potter barged into the bathroom and pushed her so she almost toppled into the bath.

The animal hospital nurse, who is now seeking a divorce, said she was left with reddening to the back and neck. She also alleged previous physical abuse during the 13-year marriage, and said she rang 999 on her mobile in fear.

Potter claimed that the discussion about the sponge took place in the lounge, and when he later went into the bathroom, he feared he was going to be assaulted again.

The ex-police officer, who was in the force for 31 years, said he grabbed the front of her clothing and pushed her back, but denied that she had almost fallen almost into the bath.

Magistrates adjourned for a pre-sentence report, but ruled out custody. Potter, now living at Llys Erw, Ruthin, was bailed on condition that he does not approach his wife.
